Hi there,is it possible to 'virtually connect' the output of the audio board with the input of the audio board?I mean without the physical cable...What I need is to reproduce an audio file and get it on the audio input line, on the same PC.

Using Audacity you could select the input for recording to be the output from your system, in my case I had to select HDA Intel PCH:ALC3234 Analog (hw:0,0) as the input and tested by simply playing a sound from another application and when I started recording it was detected and showed in the main screen.

Actually, it's a module - so the "X" for this particular loot is on /lib/modules/$(uname -r)/kernel/sound/drivers/ The problem with ALSA is not lack of functionality, or even ease-of-use (as the pulseaudio fans will say), it's lack of usable documentation.I have managed to discover a few fun tricks, mainly by trial-and-error, but loopback is not something I've ever needed - so I only went as far as "mostly works".
